Media Bias in Abortion Coverage

If roughly the same percentage of Americans hold the view that all abortion should be legal (whether the abortion takes place moments before birth or simply because the child is female or has Down syndrome) as hold the view that all abortion should be illegal (even if the child is conceived because of rape), why do the media only ask candidates about one of these positions?

When was the last time you heard a reporter ask a similar question of one of the 246 members of Congress who voted that it should always be legal to terminate an unborn child simply because she is female? Consistent pro-life politicians are routinely asked why women who get pregnant as a result of rape should be forced to continue their pregnancy. Consistent pro-choice politicians are almost never asked why they think it should be legal to kill an unborn child just because she happens to be female. Consistent pro-choice politicians are rarely, if ever, asked why it should be legal to kill an unborn child just because she happens to have Down syndrome. Heck, they’re rarely even asked why it should be legal to kill an unborn child on her way to the birth canal. Why is that?
